MEANS FOR-RAISING ANoHoRs.

SPECIFICATION forming part of Letters Patent No. 527,060, dated October9, 1894. Application led November 25. 1893. Serial No. 491,971. (Nomodel.) Patented in England October 6, 1893, No. 18.760.

To all whom t may concern.-

Be it known that we, HENRY ALONZO HOUSE, Sr., and HENRY ALONZO HOUSE,Jr., mechanical engineers, both citizens of the United States ofAmerica, and both temporarily residing at Teddington, in the county ofMiddlesex, England, but usually of Bridgeport, county of Fairfield, andState of Connecticut, United States of America, have inro vented certainnew or Improved Means for Raising Anchors, (for which we have obtained apatent in Great Britain, No. 18,760, dated October 6, 1893,) of whichthe following is a specification.

The object of this invention is to provide means or devices wherebyanchors which have been caught or held by rocks or other obstacles insuch manner as to prevent their be` ing raised in the ordinary way bypower apzo plied to the shackle end of the shank without breaking orbending them, can be raised by power applied at the opposite end ot' theanchor in such manner as to draw the lukes longitudinally out of and tofree them from 2 5 the hole or other space in which they may be engaged.For this purpose we employ the devices shown in the accompanyingsheet ofdrawings, in which- Figure 1 is the elevation of an anchor with 3o itsiuke or dukes caught in between two rocks, and having our recoveringgear applied thereto. Fig. 2 is a plan of the grappling tackle shown insectional elevation at I in Fig. l. Fig. 3 is an elevation of one half 35 of the said grappling tackle, and Fig. 4 a plan of the part marked Hin Fig. l.

The anchor shown is of the kind known as Martins but the invention isalso applicable to other kinds of anchors.

Similar letters of reference relate to like parts in all the figures ofthe drawings.

A is the shank of the anchor; B, one of the iiukes which is shownengaged between two rocks C C in such manner that power applied, in theusual way, to the main cable D in the direction of the arrow cannotraise the anchor unless the fluke B breaks or yields by bendingsuciently to allow of its being drawn out from between the rocks.

counterbalance weights I6.

Our new or improved devices consistas fol- 5o lows:

E is-a chain connected at one end by a shackle F orotherwise to thecrown B of the iiuke arm, or to any other suitable point at that end ofthe anchor. This chain E is connected at its other end by a shackle G orotherwise to a sleeve H which is free to slide on the main cable D. Theupper end of this sleeve is conical as shown at H and formed with apendent lip H which extends round 6o the lower end of the conical part.The chain E and sleeve H maybe kept permanently connected to the anchor,or be only applied thereto when it is known or suspected that the bottomis rocky or of a nature to unduly hold the anchor and prevent it frombeing weighed in the usual way.

I is a grappling apparatus (shown partly in section in Fig. 1) which islowered from the ship down the main cable D by a chain J 7o when it isfound that the `anchor has fouled something and cannot be weighed by themain cable. The grappling apparatus consists of a sleeve I which is freeto slide up and. down on the main cable D. The chain J 7 5 is connectedto the sleeve I by the shackle l2.

I3 are arms standing out-from the lower part of the sleeve I and havinghooks I4 turning on fulcra I5 at their lower ends. The ends of thesehooks are pressed normally inward 8o toward the main cable D by means ofthe When this grapplingapparatus is lowered by the chain J it slidesdown the main cable D and. the hooks I4 slide down the conical surface Hof the 85 sleeve H until their points descend below the lip H of thesleeve H when the weights IG force the hooks inward under the said lipinto position shown in dotted lines at the. right hand top corner ofFig. 1. When the 9o hooks 14 have got well under the lip H (which can beascertained by pulling the chain J up- .'ward until suficient resistanceis encountered to indicate that the sleeve H has beenl grappled andraised as far as the chain'E willal- 95 low) the main cable D isslackened out, and the chain J tightened until the main cable D and thechain E assume positions such as those shown in dotted lines in Fig. land a continuance of the pull on the chain J (which pullis transmittedthrough the grappling apparatus I, sleeve II, and chain E to the head ofthe anchor) will draw the fluke or dukes out of the hole or cavity inwhich it or they have been caught, and the anchor may then be raised tothe ship either head first by the chain J or shank [i1-st by the maincable, or more or less in a horizontal position by sim ul taneouslypulling on both chains D and J.

The sliding sleeve I of the grappling apparatus is preferably made intwo halves so that it can be easily placed on or removed from the maincable D. and for this purpose the two halves maybe hinged together atone side as at I7 in Fig. 2 and fastened together at the other side by abolt or stud passing through lugs Igor by any other suitable means.

In Fig. 2 four hooks are shown on the grap pling apparatus but it isobvious that any other number may be employed according tocircumstances.

In the foregoing specification the parts D, E and J are described aschains; but it is obvious that wire ropes or ropes of any other suitablekind may be employed instead of chains for any or all of those parts.

Ve claiml. The means or devices for raising anchors adapted to beengaged by the hooks of the grappling apparatus, a chain or rope Econnecting the sleeve H With the head or fluke end of the anchor, andgrappling apparatus I sliding on the main cable D and provided Withhooks I4 adapted to engage with the sleeve H so as to connect the chain.I With the chain E combined and operating substantially as described.

In ivvitness whereof we have hereunto set our hands in presence of twoWitnesses.
